Title: A manufacturing process of semiconductor substrate
Inventor: NANPYAKU SEO
IPC: H01L21/316
Filed: 1992-12-23
Granted: 1993-07-11
Abstract: The present invention is relative to the manufacturing process of semiconductor substrate characterized in that it consists of a process to make into oxide-film on a specialized-polarity semiconductor substrate, and a process to build the impurity of the same polarity with the specialized-polarity into the semiconductor substrate, and a process to make into acidproof-film on the oxide-film, and a process to clear the desired part of the acidproof-film, and a process to produce oxide-film and then making into element-isolation-film by heating-oxidation of the semiconductor substrate, and a process to clear the acidproof-film. That is to say, before the making of oxide-film, the impurity is introduced into from the element-area to the element-isolation-area, so the inhomogeneous part of the impurity-density-profile will not exist in the boundary-area of element isolation. As a result of it, the generation of narrow-channel-effect of transistor will be prevented. Besides, the birds-beak part also can be cleared easily.

Title: Method and apparatus to inspect the substrate by using diffraction light
Inventor: AIYER ARUN A
IPC: G01N21/94
Filed: 1997-04-15
Granted: 2000-06-21
Abstract: The objective of this invention provides a method to detect the defects in a processed or partly processed semiconductor wafer, or other similar three-dimensional periodic pattern formed on a substrate surface by light diffraction. Incident monochromatic light is provided from an elongated and extended source to illuminate the entire wafer surface. By use of automated image processing techniques, wafer macro inspection is thereby automated. The elongated and extended light source allows light at different angles to be incident upon each point of the wafer surface, thereby allowing defect detection for an entire wafer surface in a single field of view and reducing inspection time. The particular wavelength of the incident monochromatic light is predetermined to allow optimum detection of defects in the periodic pattern on the wafer, depending on the width and pitch of the features of the periodic pattern.

Title: Method for manufacturing an optoelectrical component and an optoelectrical component manufactured according to the method
Inventor: PALMSKOG GORAN
IPC: G02B6/30
Filed: 1997-09-18
Granted: 1999-12-01
Abstract: The optoelectrical components which up to now have been used in the fibre-optical region have had waveguides of quartz and glass with hermetic encapsulating, which components have had too high manufacturing costs for profitable use. Through making polymeric single mode (SM) waveguides from plastic, for example, benzocyclobutene polymer (BCB) a simple reliable and inexpensive concept for making waveguides can be obtained. Two of the commercially available grades of BCB/DOW Chemicals have furthermore a refractive index difference which permits manufacturing of buried waveguides with SM characteristics. These two types of BCB material have shown themselves to be especially usable for manufacturing of so-called buried SM waveguides: a heat curable grade (1, 4) used for under- and over-cladding for waveguides and a photodefinable derivative (3) used as the waveguide material. Encapsulating of a waveguide chip can in this way be made with plastics, at the same time as the connector interface can be formed in the end surfaces of the components.
